@dudleydes Hi there. I know this thread is quite old, bit wonder if you can help me please.

I already have Scummvm (SDL1) installed in Retropie and the games run - albeit with the less-than-ideal controller configuration.

Could I just follow your instructions (replacing scummvm with scummvm-sdl1) up to the point of editing and saving sdl-events.ccp?

I tried running through the full thing and it broke my install of Scummvm (thank the lord for backup images!), and so I'm not sure what else to try.

I should say I have no understanding of coding whatsoever, I'm just trying to work my way through this by following the explicit instructions of helpful folk like yourself.

Many thanks for any pointers you can give me.

@journeyman when binding the 'start' button will be your p1 start, and the select button will be your coin button. i don't know any shootemups that use more than 4 buttons.

Problem Solved:
It turns out it was a wiring problem: the A and B Buttons were crossed on the 2nd controller. It seems the system has no way of differentiating between the two otherwise identical controllers. So the config for controller 2 probably overwrote the config for controller 1 and vice versa each time a new controller config was put in.

@theRog05 If you're re-starting again, then get the 4.5.1 image from https://retropie.org.uk/download, which should have the necessary pre-requisites installed.

Not sure if this helps. I had problem where the 2:nd player use the P1 controls.
. Needed to add:
usbhid.quirks=0x16c0:0x05e1:0x040
To the /boot/cmdline.txt to get the player 2 control to be detected. Not sure if this is related at all.

@mimph here is the info you need:

@onsmike Yes, it seems a keyboard is needed. That's what "solved" the problem for me when I tried it last night at any rate. It's a bit annoying, but it works on the roms I tried.

How would I access the emulator settings over keyboard then ?

@AlexMurphy thank you. And there is no other addon to get them working?

@xxxARCH3Rxxx plug it in. Sync your wiimotes to it. You need to go and undo everything you just did though. So it doesnt have any conflicts.

Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first

Any solution to this?

Thanks Gerald. This worked for me! I'm assuming I'll have to do this for every additional controller I have connected, but it's not a big deal. I wonder why the main Configure Input on the emulation station doesn't work for the individual roms.
